Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-6, a hydrogen gas cylinder lifting clamp includes a suspension rod 2, a movable support 4, an operating support 5, a connecting rod 6 and a clamping head 7.
The movable support 4 comprises a sleeve 4-1 and two cross rods 4-2 symmetrically and fixedly arranged at two sides of the sleeve 4-1. In this embodiment, the movable support 4 has an inverted T-shaped structure.
The suspension rod 2 is arranged in the sleeve 4-1 of the movable support 4 in a penetrating way. Wherein, be equipped with locating part 3 on the jib 2, locating part 3 is used for controlling the highest position that removes support 4 along 2 upward motions of jib.
Specifically, the limiting part 3 is a limiting nut in threaded connection with the suspender 2.
The two groups of operating supports 5 are provided, the upper ends of the two operating supports 5 are respectively rotatably connected with one ends, away from the sleeve 4-1, of the two cross rods 4-2 of the movable support 4, and the lower ends of the two operating supports 5 are respectively fixedly provided with a chuck 7.
The two groups of connecting rods 6 are arranged, the upper ends of the two connecting rods 6 are rotatably connected with the lower end of the suspender 2 at one position, and the lower ends of the two connecting rods 6 are respectively rotatably connected with the middle parts of the two operating brackets 5.
It should be noted that the operation brackets 5 are holding parts of two hands when the hydrogen gas cylinder 14 is hoisted, and the horizontal distance and the vertical length of the two operation brackets 5 are suitable for two-hand operation.
Referring to fig. 4, preferably, the chuck 7 is an arc structure adapted to the neck of the hydrogen gas cylinder 14, and the concave arc surface is provided with a thread adapted to the thread on the neck of the hydrogen gas cylinder 14, so that the chuck 7 can clamp the neck of the hydrogen gas cylinder 14 to prevent slipping. After the two clamping heads 7 clamp the bottle neck and are closed, a gap of 2-3mm is reserved between the two clamping heads, so that the problem that the bottle neck cannot be clamped because the two clamping heads 7 are contacted due to the manufacturing error of the bottle neck of the gas cylinder is avoided.
Referring to fig. 1-2, as one embodiment, the top of the suspension rod 2 is a Y-shaped structure, and each branch thereof is provided with a hanging hole 2-1, and further includes a hanging chain 1, and two ends of the hanging chain 1 are respectively connected with the hanging holes 2-1 on the two branches at the top of the suspension rod 2. Among the above-mentioned technical scheme, the lifting chain 1 is used for hanging the jib 2 on the lifting hook of balanced hanging, does benefit to adjustment hydrogen gas cylinder 14.
Referring to fig. 5, further, an anti-drop steel rope 11 is connected to the hoist chain 1, and the anti-drop steel rope 11 is connected end to end (generally through a locking chuck 12) and a locking sleeve 13 is inserted through the anti-drop steel rope 11. Adopt the utility model discloses after pressing from both sides tight hydrogen gas cylinder 14, establish anticreep steel cable 11 front end cover after on gas cylinder valve 15, preceding locking cover 13 that pushes away carries out the pretension, forms the protection of falling, guarantees the security of hoist and mount process.
As shown in fig. 1, as one embodiment, a remote controller placing rack is fixed on at least one operating bracket 5, and the balancing crane can be operated by holding the operating bracket 5 by hand, which is beneficial to rapid operations such as hoisting. Specifically, the remote controller placing frame comprises a placing groove 10 and a limiting sleeve 9 which are arranged at an upper interval and a lower interval so as to expose an operation button on the remote controller.
Referring to fig. 6, the operation process of lifting the hydrogen gas cylinder 14 according to the present invention is as follows:
before the use, the position of the limiting nut is determined. The operating bracket 5 is held by both hands, and the chucks 7 are separated to both sides. When the chuck 7 is opened, the movable support 4 moves upwards along the suspender 2, the included angle between the two connecting rods 6 is increased, and when the included angle is close to 180 degrees, the limiting nut is adjusted to prop against a sleeve 4-1 of the movable support 4, wherein the position is the highest position of the movable support 4 moving upwards along the suspender 2. Therefore, the phenomenon that the clamping head 7 cannot be folded in the using process can not occur.
When the device is used, the device is hooked on a lifting hook of a balance crane through a lifting chain 1, the operating support 5 is held by two hands, the clamping heads 7 are separated towards two sides, the balance crane remote controller 8 is operated to control the height of the clamping heads 7, the device is moved to the side of a hydrogen gas cylinder 14 (the lifting hook of the balance crane can freely move in the moving range of the lifting hook under the traction of a person), the clamping heads 7 are closed by the two hands, the clamping heads 7 clamp the bottle neck of the gas cylinder in a very fitting manner, the balance crane remote controller 8 is operated to lift the lifting hook, and the hydrogen gas cylinder 14 is lifted easily and firmly. After the hydrogen gas cylinder 14 is 10cm away from the ground, the hydrogen gas cylinder 14 is pulled to a required position, the balance crane remote controller 8 is operated to put down the hydrogen gas cylinder 14, the chuck 7 can be easily separated after being not pulled downwards, and then the device is removed for the next round of operation.
The working principle is as follows: the hanger rod 2 generates an inward and oblique upward pulling force on the operating bracket 5 by the connecting rod 6 under the action of the upward pulling force, the operating bracket 5 is equivalent to a lever, and the clamping head 7 generates inward greater pressure so as to clamp the bottleneck of the gas cylinder.
Generally speaking, the utility model discloses a behind 7 centre gripping hydrogen gas cylinder 14's of two chucks the bottleneck, can realize pressing from both sides tightly to self under the action of 14 dead weights of hydrogen gas cylinder, structural design is ingenious, uses the simple operation, on the one hand, can guarantee that hoist and mount in-process hydrogen gas cylinder 14 remains throughout vertical, on the other hand, very big workman's intensity of labour has alleviateed to the equipment production efficiency of hydrogen gas cylinder 14 has been improved.
Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
